Abstract

In the present study, the performance of an open cycle magneto hydrodynamics (MHD)-gas turbine (GT) combined plant has been analysed by considering the combustion products of MHD in partially ionized state and through the application of exergy. The combustor in the MHD system uses preheated air and coal mix and potassium carbonate as seed material to release the combustion products as partially ionized gases together with the undissociated product gases. The GT unit burns a mixture of methane and preheated air. Both MHD and the GT components have been modelled for computing energy rates and exergy destruction rates and the combined power generated. The ionization fraction is taken as 0.4 which is significant only up to the MHD generator due to temperature reduction below ionization beyond the generator. The exergy model of the GT plant is validated with a known model and the overall efficiency of the combined plant is determined. The exergy analysis which is partly based upon the effect of gas ionization shows the MHD combustor to have maximum exergy destruction followed by the process heater. Using partial ionization during combustion process in MHD, a more realistic attempt has been made to measure the power output and efficiency of the plant.
